Challenge Problems

Push your limits with challenges.

Question 1

You conducted an experiment measuring the temperature change of water over time but realized a systematic error in your temperature readings. Describe how you would adjust your experimental design to minimize this error in the future.

💡 Hint: Think about what you can change in the equipment or procedure to prevent a repeat of the issue.

Question 2

In your upcoming experiment, you anticipate recording data on a colored solution. Besides quantitative measurements, outline how you would capture qualitative observations and what significance these observations may carry.

💡 Hint: Consider different ways that colors might indicate chemical reactions.
